The dynamic effects of bundling as a product strategy

Several key questions in bundling have not been empirically examined: Do consumers value bundles over and beyond their component products, indicating synergy? Is mixed bundling more effective than pure bundling or pure components? Does correlation in consumer valuations make bundling more or less effective? Does bundling serve as a complement or substitute to network effects? To address these questions, we develop a consumer-choice model from micro-foundations to capture the essentials of our setting, i.e. the handheld video game console market. In doing so, we provide a framework to understand the dynamic, long-term impacts of bundling on demand. We find that hardware sales diminish in the absence of bundling, and consumers who had previously purchased bundles may not always purchase pure consoles, even though consoles may be cheaper than bundles. The type of bundling chosen is critical to extracting value from consumers, with pure bundling performing significantly worse than both mixed bundling and pure components. We find that consumers perceive a negative synergy between the components of a bundle. Modeling the dynamic nature of durable good purchases also helps us uncover a finding that contradicts prior static models: positive correlation between products enables bundling to be more effective than negative correlation.
